In addition, the end cap 20 is further provided with an air inlet 23, configured to supply external air into the vaporizer 100 during inhalation.
Further referring to FIG. 3, FIG. 4, FIG. 9, and FIG. 10, the main housing 10 is internally provided with a liquid storage cavity 12 for storing the liquid substrate, and a vaporization assembly for absorbing the liquid substrate from the liquid storage cavity 12, and heating and vaporizing the liquid substrate. The vaporization assembly generally includes a capillary liquid guide element for absorbing the liquid substrate, and a heating element combined with the liquid guide element.

Specifically:
in the schematic structural cross-sectional view shown in FIG. 9 and FIG. 10, the main housing 10 is internally provided with a vapor-gas output tube 11 arranged along an axial direction; and the main housing 10 is further internally provided with a liquid storage cavity 12 configured to store the liquid substrate. In the implementation, at least part of the vapor-gas output tube 11 extends in the liquid storage cavity 12, and the liquid storage cavity 12 is formed by the space between the vapor-gas output tube 11 and an inner wall of the main housing 10. A first end of the flue gas transmission pipe 11 opposite to the proximal end 110 is in communication with the suction nozzle A, and a second end opposite to the distal end 120 is in airflow connection with a vaporization chamber 340 formed by defining between a vaporization surface 310 of the porous body 30 and the end cap 20, so as to transmit the aerosol generated by the vaporized liquid substrate in the heating element 40 and released to the vaporization chamber 340 to the suction nozzle A for inhalation.
Referring to a structure of the porous body 30 shown in FIG. 3, FIG. 4, and FIG. 9, a shape of the porous body 30 is configured to be substantially, but not limited to, a block structure in this embodiment. According to a preferred design of this embodiment, an arch shape is included, and the specific structure can be described in the application CN212590248U . In a general functional configuration, the porous body 30 has a vaporization surface 310 facing the end cap 20 in the axial direction of the main housing 10. In use, a side of the porous body 30 facing away from the vaporization surface 310 is in fluid communication with the liquid storage cavity 12, so as to absorb the liquid substrate, then the microporous structure inside the porous body 30 transmits the liquid substrate to the vaporization surface 310 to be vaporized to form the aerosol, and the formed aerosol is released from the vaporization surface 310 to the vaporization chamber 340 defined between the vaporization surface 310 and the end cap 20.
Certainly, the heating element 40 is formed on the vaporization surface 310. After assembly, the second electrical contact 21 abuts against the heating element 40, so as to supply power to the heating element 40.
Further, referring to FIG. 3 to FIG. 5, in order to assist in the installation and fixation of the porous body 30 and the sealing of the liquid storage cavity 12, the main housing 10 is further provided with a flexible seal element 50, a support 60 and a flexible seal element 70, which not only seals an opening of the liquid storage cavity 12, but also fixes and holds the porous body 30 inside.
For the specific structure and shape, the flexible seal sleeve 50 is generally in a hollow cylinder shape. The inner hollow is configured to accommodate the porous body 30, and is sleeved outside the porous body 30 in a close-fitting manner.
The rigid support 60 holds the porous body 30 sleeved with the flexible seal sleeve 50. In some embodiments, the rigid support 60 may generally have an annular shape with an open lower end, and a holding space 64 is arranged. The holding space 64 is configured to accommodate and hold the flexible seal sleeve 50 and the porous body 30. On one hand, the flexible seal sleeve 50 can seal a gap between the porous body 30 and the support 60 to prevent the liquid substrate from seeping out of the gap between the porous body and the support frame. On the other hand, the flexible seal sleeve 50 is located between the porous body 30 and the support 60, which is advantageous for the porous body 30 to be stably accommodated in the support 60 to avoid from loosening.
The flexible seal element 70 is arranged between the liquid storage cavity 12 and the support 60, and the shape of the flexible seal element is adapted to the cross section of the inner contour of the main housing 10, so as to seal the liquid storage cavity 12 and prevent the liquid substrate from leaking out of the liquid storage cavity 12. Further, in order to prevent the shrinkage and deformation of the flexible seal element 70 made of the flexible materials from affecting the tightness of the sealing, the holder 60 is accommodated in the flexible seal element 70 to provide support for the flexible seal element.
On an aerosol output path during the inhalation process, referring to FIG. 3 to FIG. 4, the flexible seal element 70 is provided with a first insertion hole 72 for a lower end of the vapor-gas output tube 11 to plug in, the support 60 is correspondingly provided with a second insertion hole 62, and an opposite side of the support 60 to the main housing 10 is provided with an aerosol output channel 63 through which the vaporization surface 310 is in airflow communication with the second insertion hole 62. A complete inhalation flow path after installation is shown by arrow R2 in FIG. 3. The external air enters the vaporization chamber 340 via the first air inlet 23 on the end cap 20, then carries the generated aerosol to flow from the aerosol output channel 63 to the second insertion hole 62, and then outputs to the vapor-gas output tube 11 via the first insertion hole 72.
On the transmission path of the liquid substrate, specifically, as shown in FIG. 3, FIG. 4, and FIG. 11, a second liquid guide hole 61 that flows to the holding space 64 in the liquid storage cavity 12 is arranged on the support 60. A third liquid guide hole 51 opposite to the second liquid guide hole 61 is further arranged on the flexible seal sleeve 50, so that the liquid substrate can be transmitted to a surface of the porous body 30 through the third liquid guide hole 51 to be absorbed, as shown by arrow R1 in FIG. 11.
Further, in order to prevent leakage of the liquid substrate in the liquid storage cavity 12 of the vaporizer 100 before being used by the user, in still another preferred embodiment of this application, referring to FIG. 5 to FIG. 11, the main housing 10 and the end cap 20 after liquid injection in the vaporizer 100 have a first assembly position shown in FIG. 5/FIG. 10 and a second assembly position shown in FIG. 6/FIG. 11. At the first assembly position, the liquid storage cavity 12 and the second liquid guide hole 61 are isolated or sealed, and at the second assembly position, the liquid storage cavity 12 and the second liquid guide hole 61 are unblocked.
Referring to FIG. 3 and FIG. 4 structurally, the main housing 10 and the end cap 20 are provided with limiting structures that are engaged with each other, and is configured to provide a limit to the flexible seal element 70 at the first assembly position and the second assembly position during the assembly process. During specific implementation, the limiting structure includes: a first engagement groove 13 and a second engagement groove 14.
Specifically, the main housing 10 has the first engagement groove 13 and the second engagement groove 14 arranged in sequence in the longitudinal direction. The first engagement groove 13 is close to the distal end 120 of the main housing 10. The end cap 20 has a first snap 24 and a second snap 25 arranged in sequence in the longitudinal direction.
When the main housing 10 and the end cap 20 are in the first assembly position shown in FIG. 5/FIG. 10, the first snap 24 on the end cap 20 forms an engagement with the first engagement groove 13; and the second engagement groove 14 and the second snap 25 are in a non-engagement state. In this case, as can be seen from the figure, a distance 80 still exists between the end cap 20 and the main housing 10 in the first assembly position, which is not completely tightly combined. Further, in accordance with the arrow R3 in FIG. 10, the end cap 20 is further pressed against the main housing 10, the first snap 24 of the end cap 20 is further snapped into the second engagement groove 14 of the main housing 10, the second snap 25 of the end cap 20 is snapped into the first engagement groove 13 of the main housing 10, and the end cap 20 is closely combined with the main housing 10 to form the second assembly position shown in FIG. 6 and FIG. 11.
Further, in conjunction with the above different assembly positions, the vaporizer 100 has a configuration in which the liquid storage cavity 12 is brought into communication or not in conjunction with the above operations. Specifically, the flexible seal element 70 for sealing the liquid storage cavity 12 is provided with:

a blocking portion 71, opposite to the second liquid guide hole 61, where the blocking portion blocks or seals the second liquid guide hole 61, thereby preventing the liquid substrate in the liquid storage cavity 12 from flowing into the second liquid guide hole 61; and
a rupturable weak region 73, configured to be defined by a groove around the blocking portion 71 in the preferred embodiment shown in FIG. 8, thereby allowing the rupturable weak region 73 to have a very thin thickness less than the rest of the seal element 70 to facilitate the rupture or breakage, such as a thickness of about 0.1 mm. In use, the rupturable weak region 73 may rupture to cause the blocking portion 71 to come off or fall off to bring the liquid storage cavity 12 and the second liquid guide hole 61 into communication, as shown in FIG. 11.

Further, in order to break the rupturable weak region 73, as shown in FIG. 7 and FIG. 11, a squeezing member 112 extending longitudinally is further arranged in the main housing 10. The shape may be in a shape of a sheet or a rod, and the squeezing member has a free end facing the distal end 120, and the free end is configured to squeeze a squeezing end 111 of the blocking portion 71. The operation process of production and use, referring to FIG. 9 to FIG. 11 in sequence, includes the following.
S10: Referring to FIG. 9, the main housing 10 after the liquid injection of the liquid storage cavity 12 is completed is inverted, and then the end cap 20 fitted with the seal element 70, the support 60, and the like is pressed into an open end of the main housing 10 until the first snap 24 on the end cap 20 is engaged with the first engagement groove 13 and assembled to form the first assembly position in FIG. 10. In this case, a distance 80 still exists between the end cap 20 and the main housing 10, which is not completely tightly combined; and the blocking portion 71 of the seal element 70 abuts against the squeezing end 111, but the rupturable weak region 73 is not broken, and the liquid storage cavity 12 and the second liquid guide hole 61 of the support 60 are isolated or sealed.
S20: When the user requires to use, the end cap 20 is further pressed towards the main housing 10 as indicated by arrow R3 in FIG. 10 until the first snap 24 of the end cap 20 is snapped into the second engagement groove 14 of the main housing 10, the second snap 25 is snapped into the second engagement groove 13 of the main housing 10, and the second assembly position shown in FIG. 11 is formed. During this process, the blocking portion 71 of the seal element 70 is further squeezed by the squeezing end 111, so that the rupturable weak region 73 may rupture to cause the blocking portion 71 to come off or fall off to bring the second liquid guide hole 61 of the liquid storage cavity 12 and the support 60 into communication. The liquid substrate can flow to the porous body 30 along the arrow Rl, and then be heated and vaporized to generate the aerosol for the user to inhale.
Further, as can be seen from the above description and figures, the seal element 70 provides a seal between the liquid storage cavity 12 and the support 60 in both the first assembly position and the second assembly position, preventing leakage of the liquid substrate in the gap therebetween.
Further, according to FIG. 8, in order to cause the squeezing end 111 of the squeezing member 112 have sufficient strength in squeezing the blocking portion 71, the squeezing member 112 is connected to a pipe wall of the vapor-gas output tube 11. Certainly, in a preferred implementation, the main housing 10 with the vapor-gas output tube 11 and the squeezing member 112 is prepared by molding a moldable material through a mold.
In some other optional variant embodiments, FIG. 12 shows a schematic structural diagram of a seal element 70a and a support 60a according to still another embodiment.
The support 60a has a second liquid guide hole 61a, and is configured for the liquid substrate in the liquid storage cavity 12 to flow to the porous body 30;
the seal element 70a has a first liquid guide hole 74a opposite to the second liquid guide hole 61a, and a blocking portion 71a located in the first liquid guide hole 74a; and the blocking portion 71a is connected or held in the first liquid guide hole 74a through the rupturable weak region 73a. After assembly, the blocking portion 71a blocks or seals the second liquid guide hole 61a; and when the squeezing end 111 of the squeezing member 112 squeezes the blocking portion 71a, the rupturable weak region 73a can be broken, and the blocking portion 71a can be come off or fallen off, thereby turning on the second liquid guide hole 61a.
In addition to the seal element 70/70a described above, an expandable slit or notch may also be used to form a weak region, which is enlarged when the squeezing end 111 of the squeezing member 112 is squeezed, thereby unblocking the liquid storage cavity 12 and the second liquid guide hole 61/61a.
FIG. 13 and FIG. 14 show schematic structural diagrams of a vaporizer according to another embodiment. A squeezing member 112b is integrally formed on the vapor-gas output tube 11b of the main housing 10b. A squeezing end 111b of the squeezing member 112b is constructed in a shape of a spike or a tip to facilitate easy puncturing or breakage of the rupturable weak region 73b of the seal element 70/70b during squeezing. Certainly, according to FIG. 13, the squeezing end 111b of the spike or tip is opposite to the rupturable weak region 73b in position. During operation, the squeezing end 111b abuts against the rupturable weak region 73b and is squeezed so that the squeezing end is punctured or broken.
FIG. 15 and FIG. 16 are schematic structural diagrams of a squeezing member 112c according to another embodiment. In this implementation, the squeezing member 112c is mainly annular in shape, and is substantially bound to a lower end of the vapor-gas output tube 11c by means of riveting or injection molding, or interference. The squeezing member 112c also has a tip-shaped or spike-shaped squeezing end 111c, to facilitate easy puncturing or breakage of the rupturable weak region 73/73a of the seal element 70/70a during squeezing. The squeezing member 112c has a small size or volume, which is advantageous for improving space and liquid storage capacity of the liquid storage cavity 12c.
